This article applies to the current NAC Enforcer, Web UI, and the latest NAC Policy Key installed on Windows or macOS systems.
This article lists all antivirus products and vendors currently supported by OPSWAT’s MetaDefender NAC.
Such support comprises the following functions:
- These policies are evaluated in the order of (1) Installed, then (2) Running, then (3) Definitions.
- If a Policy Key does not show an antivirus as Running, it can not yet evaluate whether Definitions are up to date, etc.

Policy Key endpoint web-responsive messages
Antivirus Not Installed

- This page will be displayed on endpoints that have the NAC Policy Key running but are quarantined for not having an antivirus product installed.
- Popular antivirus vendor websites are listed, and blocked clients will have direct access to those websites via the message page, so that they can download a suitable, supported product and thus remediate their non-compliant state.
Antivirus Definitions Out-Of-Date/Antivirus Is Not Running

This message will allow blocked clients to access vendor-specific resources, based on the vendor product detected on their endpoint device.
The Vendor Resources link in the example above points to the ESET website.
For queries, concerns or issues regarding NAC’s Supported Antivirus Products, please open a Support Case with the OPSWAT team via phone, online chat or form, or feel free to ask the community on our OPSWAT Expert Forum.
